1) 7 MACE AND 2 CANDAREENS = One Silver Dollar (1 Yuan) ;
2) ONE TAEL = Five Silver Dollars (5 Yuans)
For all the period of Warring Warlords, the 7 MACE AND 2 CANDAREENS are of 39 mm real Silver Dollars in size; Only later, the 45 mm real Silver Dollar Coin of One TAEL (Five Silver Dollars) showed up..
The only abnormality during this period is when the Copper versions of 45 mm ONE TAEL (Five Silver Dollars) coins became widely circulated...They are not fakes or replicas..They are the real McCoy!
Just like the 88 mm Silver Dollar Coins of the same Era, they are the Crown Jewels! And even the 45 mm Silver Dollars become rare and valuable!!
